The World Sportscar Championship was the world series run for sports car racing by the FIA from 1953 to 1992. The championship evolved from a small collection of the most important sportscar, endurance, and road racing events in Europe and North America with dozens of gentleman drivers at the grid to a professional racing series where the world's largest automakers spent millions of dollars per year.
